During rinse cycle (at least) , only when hot or warm water temp is selected, the hot water inlet hose vibrates violently, shaking the pipes in the wall. Its almost more of a vibration, like the valve is turning on and off a couple times per second.
How to determine if this is electronic or if its the hot water valve?
You will want to check the screens on the water valve where the water hose connects. There is a chance that the screen is clogged and causing pulsing water pressure which will cause the jumping vibration noise. If this checks ok then the water valve is the most likely culprit for this issue.
